The Lowdown
Alright, Rusty here. Let’s break this down.
Right off the bat, it’s a lean stretch. Karramarro, that point break, is looking at a whole lot of nothing for the first week and a half. The (combined swell energy) is mostly sitting below 100, with weak numbers like 38, 61, 77, barely climbing over 100 by the 16th. The wind is all over the place, and even when we get a glassy morning like Thursday the 13th morning, the swell is a tiny 1ft from the WNW with a 10-second period – you’d be bobbing around more than riding. Water temp is 76°, about 5° warmer than normal, so it’s like a bath.
The pattern keeps teasing with clean windows on the 16th morning and 17th morning, but the swell is only 3ft to 3ft with short periods under 8 seconds. For an inconsistent point break, that’s just not enough grunt. The crowds can be an issue here when it’s good, but honestly, there won’t be many out for this weak stuff.
Then you get to the real standout, and it’s a long way out. Monday the 24th of August morning. That’s the one. We’re looking at a solid 8ft swell out of the NW, with a 9-second period, and the combined energy jumps to 980 – that’s serious power. The wind is a light cross-off from the WNW, and it’s clean. That’s a top-tier window for advanced surfers only – over 8ft is expert territory. The afternoon gets a bit choppier with a crosswind, so hit it early. Tuesday the 25th morning still has some good leftover size at 5ft from the NW with glassy conditions, but it’s a step down.
Basically, you’re waiting until the 24th. Before that, save your energy. That one morning is the real deal.
Rusty.

Information about the Karramarro Surf forecast
The above surf forecast table for Karramarro provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Karramarro can be found by selecting the local surf guide option on the grey menu. Our Karramarro surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Karramarro) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Karramarro may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
